If you are using the armv7l docker image, the OpenJS Foundation that publishes node is no longer producing 32-bit builds as of v24. That means the last supported LTS version of node for armv7l is v22, which will go End-of-Life in May 2027.
Therefore, the Reactor armv7l image is now deprecated and will only be produced until node v22 goes EOL, and I will not publish armv7l images beyond that date.
If you are running an RPi 3 or earlier with Reactor, you are on this image, and will need to upgrade hardware to a 64-bit model and use the arm64 image. If you need help getting it done, ask in this category.
